PURPOSE:To provide refractories for spraying having remarkably improved sticking property, especially dropping phenomenon in a spraying process. CONSTITUTION:Basic aluminum lactate modified with an inorg. acid is used as an essential component of refractories for spraying. The amt. of the inorg. acid is 0.5-20wt.% of the amt. of the modified basic aluminum lactate. Sulfuric acid, phosphoric acid or boric acid can be used as the inorg. acid. A hardening accelerator may be added to the refractories. |
